The Chasnikov trunk corridor was one of the ceramacrete trunk corridors in Hancock Tower, one of the seccy residential towers in the Mesan capital city of Mendel.
Located in the western side of the tower, the tower's defenders planned to use demolition charges to collapse portions of the corridor onto the troopers of the Mesan Internal Security Directorate when they attacked the tower in 1922 PD. (CS3)
